（通过freemarker模板）如果用freemarker模板可以这样写，别的模板类推
根据自己的意愿修改条件和输出，把你的datetime传进去即可
<#macro timeline_dt datetime=.now> <#assign ct = (.now?long-datetime?long)/1000> <#if ct gte 31104000><#--n年前-->${(ct/31104000)?int}年前 <#t><#elseif ct gte 2592000><#--n月前-->${(ct/2592000)?int}个月前 <#t><#elseif ct gte 86400*2><#--n天前-->${(ct/86400)?int}天前 <#t><#elseif ct gte 86400><#--1天前-->昨天 <#t><#elseif ct gte 3600><#--n小时前-->${(ct/3600)?int}小时前 <#t><#elseif ct gte 60><#--n分钟前-->${(ct/60)?int}分钟前 <#t><#elseif ct gt 0><#--n秒前-->${ct?int}秒前 <#t><#else>刚刚 </#if> </#macro>
方法三：
找到一个专门的插件PrettyTime
public static void main(String[] args) { PrettyTime p = new PrettyTime(); System.out.println(p.format(DateUtils.addDays(new Date(), 2))); }
方法四：
自定义Java方法：
private final static long minute = 60 * 1000;// 1分钟 private final static long hour = 60 * minute;// 1小时 private final static long day = 24 * hour;// 1天 private final static long month = 31 * day;// 月 private final static long year = 12 * month;// 年 /** * 返回文字描述的日期 * * @param date * @return */ public static String getTimeFormatText(Date date) { if (date == null) { return null; } long diff = new Date().getTime() - date.getTime(); long r = 0; if (diff > year) { r = (diff / year); return r + "年前"; } if (diff > month) { r = (diff / month); return r + "个月前"; } if (diff > day) { r = (diff / day); return r + "天前"; } if (diff > hour) { r = (diff / hour); return r + "个小时前"; } if (diff > minute) { r = (diff / minute); return r + "分钟前"; } return "刚刚"; }
方法五：
